Dryer was failing to dry clothes (heat going off intermittently)

To be more precise, the clothes weren't getting dry and there was some sort of vibration sound coming out of the dryer. I removed the front panel (by removing the 4 front screws (2 in the door and 2 on the opposite side). I then ran the dryer while inspecting the innards. I notice that the igniter was lighting but was failing to start the gas flame. I could smell a little gas during this period so I know that gas was available but was not getting released in the correct amount. This told me that the gas valve we malfunctioning. I remove the gas valve and broke the igniter (it's fragile so be careful). Some other contributer did the same thing :(
I replace both the igniter and gas valve and presto... it was fixed. My wife was impressed and I looked good. I guess that's all that matters :)
